Well, we produce DbDOM, an open-source, persistent DOM implementation written 
in Python which can be used with 4XPath and 4XSLT (and 4RDF, 4XPointer, 
4XLink,...)

The latest version, 0.10.1 is not as fast as it could be: it so happens that 
we are in the middle of a fundamental re-write that is basically making it as 
fast and scalable as the underlying datastore (which can be SQL database, 
DB/DBM or the file system).  Version 0.10.2 is expected to be released in a 
fortnight.  Meanwhile you could check the base functionality to see if it 
matches your needs.  Of course, given that you mostly want to use Xalan or XT, 
it might now work for you.

DbDOM is bundled in 4Suite.  See
